Lightweight, Energy Ansorbing Sandwich Composite Structures with Bamboo Fiber Reinforced Plastic (BFRP) Core by using Additive Manufacturing

Abstract

Sandwich structures are extensively employed in lightweight parts/structures of military aircraft because of their high specific strength and stiffness. One undesirable property of sandwich structures is that they perform poorly with respect to energy absorption, and that can cause negative effects on vibrational damping, noise, and impact resistance. In this project, bamboo fiber reinforced plastic (BFRP) and additive manufacturing, also known as 3D printing, were suggested as a new core material and manufacturing technology in order to improve the energy absorption properties of sandwich structures. Bamboo fiber with its intriguing properties and sustainability has received significant interest as a reinforcement of fiber composites. Here, the bamboo fiber extraction technique along with a thorough understanding of the bamboo fiber as a reinforcement of polymer composite has been investigated to develop BFRP composites which have high strength and energy absorption.
